Vanessa Carlton takes the cake when it comes to wedding surprises -- by a landslide! The "A Thousand Miles" singer tied the knot with Deer Tick's lead singer and guitarist John McCauley on Friday, her rep confirms to Us Weekly. Plus, the new bride shared that Miss Stevie Nicks officiated the ceremony!

"Married this gentleman two hours ago xo," the 33-year-old musician wrote via Twitter late Friday night. Alongside the caption, the newlywed shared a photo of herself and her new husband beaming at each other while holding hands. Carlton looked stunning for her special day, wearing a tight-fitting, long-sleeved white wedding gown, and donning a purple head piece and matching flowers.

Shortly after, the blushing bride also posted a picture of the couple saying "I do" in front of the Fleetwood Mac songstress. "Thanks Stevie for marrying us!" Carlton gushed. In the photo, Nicks, 65, is seen smiling at Carlton as she officiates the ceremony. She also wears a matching head piece, while McCauley dresses casual in green pants and a brown button-up.

Carlton recently revealed a heartbreaking health scare she experienced back in early November. While pregnant, the singer was diagnosed with a fallopian pregnancy, which is when the embryo settles in the tube and doesn't allow the fetus to develop. But after chemotherapy, she experienced internal bleeding and her tube had to be removed. She shared that her new groom helped her through it all. "I realize I am a lucky woman on many levels here," she wrote on her website.

This is the first marriage for the "Ordinary Day" star. She previously dated Third Eye Blind's Stephan Jenkins from 2002 to 2007.
